Overview
Credit: 3 PDH
Length: 47 pages
This 3-hour course is the second in a series of three courses about the mechanical design of electric power distribution systems. The volume addresses conductor issues including sag, ruling spans, design tensions, Aeolian vibration, and clearances.
This course is divided into ten short chapters. It begins with an explanation of sag and tension in bare conductors. Ruling spans are explained including the various types of ruling spans. Conductor tensions and tension limits are reviewed. Example calculations are provided. Aeolian vibration is discussed as well as how to minimize the effects of Aeolian vibration. NESC conductor clearances are explained and methods for calculating proper clearances are discussed.
